摘要： Diaphragm valve having a valve body with an inlet and an outlet, a sealing membrane, and a connecting piece connecting the sealing membrane to a pressure piece of a drive. The valve body, the sealing membrane and the connecting piece are rigidly connected together to form an interchangeable, sealed valve body unit that can be connected to the drive. The connecting piece is molded on the sealing membrane, and the valve body and the sealing membrane are welded ultrasonically to one another.
